Also Compsiting in layers in photoshop is doable for animation too, and easiler than rotoscoping in computer too! Render stills with an alpha. Import stack to photshop and run a macro (actions based on the process you did to get the first image). Rebuild the stacks as an animation. I didn't do any hand painting in my image above, so I could animate it. I have the original PZ3 and my photoshop master layers too, so it can be done. (It's a good idea to save often, with different versions, when working in layers.) bB
